Shank Button for a Craft Wholesaler in Brazil
A Craft Wholesaler approached us with a shank button requirement for the Brazil market. The brief was specific: a defined look, a hard launch date and a unit cost that had to survive freight and duty. This case study records what was specified, what went wrong in sampling and how the bulk order was delivered.
The challenge
- Elastic that lost recovery after three washes
- Cartons packed to the factory ratio instead of the buyer's size ratio
- Reorders that quietly changed supplier and changed the hand feel
What we specified
| Item | Shank Button |
|---|---|
| Client type | A Craft Wholesaler |
| Market | Brazil |
| Order volume | 20,000 pieces across 4 specifications |
| Base material | POM Plastic |
| Standard size | 8# Gauge |
| Finish | Anodised Finish |
| Sampling rounds | 2 |
| Delivery window | 6 weeks from PO to ex-factory |
| Compliance | ISO 14001 |
How it was resolved
- We rebuilt the specification around POM Plastic and locked the tolerance before bulk.
- The finish was moved to Soft-Touch Rubber Coating after strike-off tests showed better durability.
- A pre-production sample was approved and retained as the golden reference.
- Production ran with in-line inspection and a mid-run photo report.
- Cartons were packed to the client's own barcode and ratio specification.
Result
- 20,000 pieces delivered inside the 6-week window.
- Unit cost held within 2.0% of the original quotation.
- Inspection-related rejection stayed under 2.0%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.
